SEAWAY SWAN against its type
It is one of 28 vessels in the other ship types category here under the Norway flag, 5.6% of the 499 on the register. The returns for 2022–2025 all give Oslo as port of registry.
Its 3,575 t of CO₂ for 2025 is 30% below the median of 5,122 t among the 335 vessels in the other ship types category on this register that reported for 2025. Per nautical mile it emitted 575.7 kg CO₂, 2.5 times the type median of 231.1 kg. It logged 526 hours at sea against a median of 2,231 hours for its type that year. 7.9% of its 2025 emissions were at berth; the median for vessels in the other ship types category was 3.9%. Across 3 years with reported emissions, the highest was 2023 (4,203 t) and the lowest 2022 (3,387 t). Of the 5 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 70 of 119 qualifying other ship typess by EEOI, at the 58th percentile. The dashed line is the type median, 69.3; this vessel reported 81.6.
EEOI divides emissions by transport work, which for this vessel and year was 43,791,891 tonne-miles over 6,210 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.6% higher than in 2022, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 14.9% and CO₂ per nautical mile fell 9.8%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
